Fibers are like tiny little rods or tubes-much longer than they are wide. Just about any fiber that you can think of is a polymer. (I guess that if it's a metal, it's called a wire, not a fiber!). Fibers can be natural-from plant or animals, or synthetic-made by people.
Accessory uses and structures. (A) A structure or use which is clearly incidental to a principal structure or use, and is located on the same lot with the principal structure or use, is an accessory use. All accessory uses are subject to the restrictions in this section.
Secondary suite. Secondary suite (or accessory suite) is an urban planning term used mainly in North American English for a self-contained apartment in an owner occupied single-family home/ lot that is either attached to the principal dwelling or in a separate structure on the same property. In British English the term annexe is used instead.
